Design Features 3

KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company

Compliance Standards

The Fast EtheRx Switch complies with the 10/100Mbps functions as defined by

IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD

Ethernet standards.

Design Features

Switching Function

The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-T

Ethernet networks to 100BASE-TX Fast Ethernet networks and to segment 10Mbps

or 100Mbps network segments.

Auto-Negotiation

Auto-Negotiation provides the means of automatically establishing a link by

detecting the link capabilities of the connected device on the network to select the

best operational mode available (i.e. 10/100BASE-TX selection, half- / full-duplex

mode operation, etc.)

Full-Duplex

Full-Duplex transmission means that dedicated inbound and outbound channels are

established for bi-directional transmission of data. This allows the collision

detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission

delay normally caused by listening, collisions, and packet resends when operating in

half-duplex mode.

Store-and-Forward Switching

The Fast EtheRx Switch uses a packet-forwarding method called

Store-and-

Forward

, which minimizes the re-transmission of faulty data packets. This means

that the Fast EtheRx Switch can store the incoming frame in an internal buffer and

check the packet for errors before sending it out to the destination port. If the frame

does contain errors, it will be discarded and then retransmitted.

Flow Control

The Fast EtheRx Switch implements a collision-based flow control mechanism that

reduces the risk of data being lost at the congested ports. This is accomplished by

forcing a collision with the data frames on all ports once the free-buffer queue has

reached the pre-set minimum.

Hardware Installation

Before you begin installing network cables, please take a few moments to

familiarize yourself with Fast EtheRx Switch. The functions on the front and

rear panels are illustrated in the following sections.

Fig. 1-KNS1600/R Front Panel

Front Panel

Power LED

The PWR LED indicates the power status of the Fast EtheRx switch. The LED

will light up steady green when the AC power cord is connected to the unit

from a power source and the power switch on the unit has been turned on.

100BASE-TX (100TX) LED

The 100TX LED will automatically light up when 100Mbps operation is

detected. This LED will not light up if 10Mbps operation is detected.

LINK/ACT LED (for both 10 and 100Mbps)

The LINK/ACT LED uses a single LED to display two functions. A steady

green light indicates that a good link has been established, and a flashing green

light indicates when data is being received or transmitted. If the LED does not

display solid green indicating a good link, check the following:

1. Make sure that the power is turned on for both the Fast

EtheRx Switch and the attached device.

Verify that the drivers for the network adapter have been

loaded on the PC. Some network adapters require that the

driver be loaded before establishing a proper link.

Front Panel 5

KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company

Make sure the cable is wired properly and connected on both

ends.

Make sure the correct cable type has been selected.

If steps 1 through 4 are correct, please check the cable, as it

may be defective or wired incorrectly. Replace the cable and

try again. Please refer to Appendix A for Pin Assignments

and Appendix B for Cabling Guidelines.

Full Duplex and Collision LED

The FDX/COLL LED uses a dual color LED to display two functions. A solid

green light indicates that Full-Duplex operation has been detected. A flashing

amber light indicates that a collision has occurred in half-duplex mode. Full-

Duplex mode is auto-negotiated on all UTP ports.

UTP Ports

The Fast EtheRx Switch has sixteen (16) 10/100Mbps UTP ports that auto-

negotiate 10/100BASE-TX connections and half- or full-duplex mode

operation. The last UTP port has two RJ-45 port connectors for support of

UTP cabling in the crossover or straight-through wiring configuration. Only

one of the two ports may be utilized.

The RJ-45 port marked

is internally crossed like all other UTP ports. By

default, all repeater and switched UTP ports are generally configured as

standard MDI-X, or internally crossed ports. With a straight-through cable, this

port can be used for cascading to a standard MDI device, such as a network

adapter or router. With a crossover cable, this port can be used for cascading to

another MDI-X device, such as a hub.

The RJ-45 port marked

Kingston Technology Company KNS1600/R User’s Guide - Rev. A00

The following diagrams show the relationship between cable type and which

UTP port connector to use. To verify

the pin wiring of your UTP cable, see

“Appendix A Pin Assignments.”

Notes on MDI and MDI-X

MDI (Media Dependent Interface) is the standard that defines the mechanical

and electrical configuration of a UTP port. For any two devices to

communicate with each other on the network, the transmitter of one device

must be connected to the receiver of the other device. This can be achieved by

using a crossover cable, or by using the MDI-X port, which implements the

crossover internally.

Ports 1 through 15, like all normal hub ports, are configured as MDI-X. Port 16

supports both MDI and MDI-X configurations. All NICs (Network Interface

Cards) and Router ports are usually by default configured MDI.

Note: Do not use both ports labeled port 16, only one connection can be used.

UTP Cable Wiring Standards

There are two governmental agencies: the Electronic Industry Association

(EIA) and the Telecommunications Industry Association (TIA), which set the

standard for all cable wiring requirements for commercial buildings.

With the advent of 100Mb/s networking products, it is best to use higher

quality CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch

panels, patch cables, and connectors while following the EIA/TIA wiring

standards. 100 Ω UTP CAT 5 type cables use 4-pair UTP wiring.

Refer to the illustrations below for 4-pair wiring using either T568A (Fig. B-1)

or T568B (Fig. B-2) wiring standards. Both T568A and T568B wiring is

compatible with 10BASE-T and 100BASE-TX and require no special

configurations, but for premise wiring, stick to one wiring standard. Mixing

T568A and T568B wiring schemes may cause or lead to potential problems.

UTP Cable Rating Codes

UTP cables meet different UL-NEC requirements based mostly on cable-jacket

quality. Below is an explanation of the rating codes for each cable type.

UL – The National Electrical Code (NEC), published by the National Fire

Protection Association (NFPA), details advisory safety considerations for

electrical wiring. NEC Article 800 Communications Cables are manufactured

to meet these different cable types.

CMP – Cables meeting type CMP requirements are suitable for

installation in ducts and plenums without the use of conduit. These cables

are designed for fire resistance and low-smoke and toxin producing

characteristics.

CMR – Riser type cables are engineered to prevent the spread of fire from

floor to floor and are suitable for vertical shaft applications.

CM – Cables for general building wiring. CM cables are used in areas

other than plenums and risers. These cables are resistant to the spread of

fire and pass the UL 1581Vertical Tray Flame Test.

MP, MPR & MPP – Within Article 800, the Multi-purpose Cables

Category, allows conditional substitutions between different cable types &

are restricted by number, AWG size and stranding of the cable conductors.

Terms You Should Be Familiar With

BACKBONE WIRING – The physical/electrical interconnections

between telecommunications wiring closets and equipment rooms.

COMPLIANCE – A datacomm or wiring device that meets all

characteristics of a standard is said to be in compliance with that standard.

PREMISE WIRING – The entire wiring system on the premises,

especially the supporting wiring that connects the communications outlets

to the network interface jack.

NEAR-END CROSSTALK (NEXT) – In wires packed together within a

cable, the signals generated at one end of the link can flush out the weaker

signals coming back from the recipient.

Appendix D Frequently Asked Questions 15

KNS1600/R User’s Guide - Rev. A00 Kingston Technology Company

Appendix D Frequently Asked Questions

What is a switch and what does it do?

Switching hubs are low-latency devices that allow you to maximize the

bandwidth of a network using concurrent access within the unit. Switches

allow you to segment LANs, connect LANs of different speeds, or extend the

collision domain of an existing LAN.

What’s the difference between a repeater and a switch?

A repeater is a device that extends the diameter of a network by regenerating

and forwarding received Ethernet packets. It repeats incoming signals to all

other ports on the device.

Like a repeater, a switch can also extend the diameter of a network. However,

a switch can also extend the collision domain of a network, like bridging a

10Mbps Ethernet LAN with a 100Mbps Fast Ethernet LAN. See the

illustration below. A switch can also be configured to operate in half-duplex or

full-duplex mode, whereas a repeater can only operate in half-duplex mode.
